Bowens disease is a form of skin cancer confined to the top layer of the skin.
Bowens Disease is characterized by a persistent, non-elevated, red, scaly or crusted plaque with a small potential to turn into an invasive Squamous Cell Carcinoma (SCC).
They can occur anywhere on the skin or mucosal surfaces, most frequently on lower legs of elderly women. They are small, red, slightly scaly and symptomless.
The surface is usually flat, but may become thickened or crusted. Ulceration is usually a sign of development into an invasive SCC.
Treatments available are very similar to those for solar keratosis: cryotherapy (freezing), a variety of topical creams, curettage, photodynamic therapy, laser and surgical excision.
